The U.S. Environmental Protection Agency (EPA) and Cummins Inc. announced that Cummins will be voluntarily recalling roughly 500,000 model year 2010-2015 medium- and heavy-duty trucks. The recall will replace a faulty emissions control systems component that causes excess emissions of nitrogen oxides (NOx).Posted February 23, 2018. INSITE has an automated SCR test that does a warm up, deposit burn, tests the NOx sensors then tests the SCR efficiency. I ran it twice and it failed both times. The dosing test put out 100 ml with a nice spray and the DEF was 32.5%. I trust the test and the truck is fixed every time.This can result in higher emission levels and test failure. 6. Catalytic Converter Problems: A damaged or inefficient catalytic converter can lead to higher levels of pollutants in the exhaust gases. Over time, catalytic converters can degrade or become clogged, reducing their effectiveness in reducing emissions. 7.The truck is a 16 freightliner M2. has a cummins isb6.7 cm2350 b101.
